nsq version：1.0
os：centos 7.4

codes:
public static void main( String[] args )
{
NSQLookup lookup = new DefaultNSQLookup();
lookup.addLookupAddress("192.168.1.228", 4161);
NSQConsumer consumer = new NSQConsumer(lookup, "TestTopic", "dusti", (message) -> {
System.out.println("received: " + new String(message.getMessage()));
message.finished();
message.requeue();
});

    consumer.start();
}

below is run time messages:

I came across the same problem when receiving messages from nsq.

The java code below

`
protected MsgConsumer(MsgConfig config, String topic) {

    NSQLookup lookup = new DefaultNSQLookup();
    lookup.addLookupAddress(config.getHost(), config.getPort());
    logger.info("start to init nsq consumer, host={},port={},topic={}", config.getHost(), config.getPort(), topic);

    NSQConsumer consumer = new NSQConsumer(lookup, topic, channel,new NSQMessageCallback (){
        @Override
        public void message(NSQMessage message) {
            try {
                message.finished();
                String msg = new String(message.getMessage(), "UTF-8");
                System.out.println("接收 rev："+msg);
                if (Strings.isNullOrEmpty(msg)) {
                    logger.info("consume msg is empty.");
                    return;
                }
                onMessage(msg);

            } catch (Exception e) {
                message.requeue();
                logger.error("failed to consume message({}), cause: {}",
                        message, Throwables.getStackTraceAsString(e));
            }
        }
    });
    consumer.start();

}

`
